Endovascular techniques and devices for the treatment of intracranial aneurysms: a review of neurointerventional outcomes

Endovascular technology for the treatment of intracranial aneurysms continues to evolve at a rapid pace. In addition to coil embolization, balloon and stent-assisted coiling have been employed for the endovascular treatment of wide-necked or otherwise morphologically challenging intracranial aneurysms, and each technique confers unique advantages. Flow-diverting stents may also be used as a primary treatment modality for complex aneurysms and have a number of benefits and limitations. This article provides a review of the evidence supporting the use of newer coiling techniques and materials, as well as adjunctive technologies such as balloon-assisted and stent-assisted coiling, for the treatment of unruptured and ruptured intracranial aneurysms.
